As far as I am aware, the vast majority of politicians in the US do not receive Secret Service protection. "every one of them needs multimillion dollars worth of protecting" is a straw man. Of course the vast majority of politicians, which includes a lot of city council members of tiny towns and so forth, do not need a 24hr security detail. And they don't have them either. It happens for the handful, not the majority. Which seems to be what you want, but your tone is frustrated or angry.
